We tested whether loneliness is associated with systematic alterations in value\u2010based social decision\u2010making and examined mechanisms that may sustain withdrawal. Across two preregistered online studies (total\n                    <jats:italic>N<\/jats:italic>\n                    = 6517), participants were randomly assigned to positive, negative, or neutral social expectation priming and completed a vignette\u2010based task manipulating reward, effort, and threat. Loneliness and psychopathological symptoms were assessed by self\u2010reports. Across both studies, higher loneliness was consistently associated with a lower likelihood of engaging in social interactions, independent of vignette characteristics and expectation priming. Higher loneliness was consistently associated with lower anticipated connectedness and greater perceived rejection risk during social decision\u2010making. Further exploratory analyses indicated that loneliness was associated with reduced sensitivity to both social reward and social threat, accompanied by diminished differentiation between high\u2010 and low\u2010reward contexts, consistent with a compressed range of subjective social value across decision scenarios. These findings suggest that loneliness is linked to altered social valuation, characterized by blunted differentiation of social rewards and reduced motivational salience of potentially beneficial interactions, contributing to persistent withdrawal across diverse everyday social contexts.\n                  <\/jats:p>","DOI":"10.1111\/nyas.70382","type":"journal-article","created":{"date-parts":[[2026,8,26]],"date-time":"2026-08-26T11:58:11Z","timestamp":1787745491000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Loneliness Biases Social Engagement Decisions: Evidence From Value\u2010Based Choice Models"],"prefix":"10.1111","volume":"1562","author":[{"given":"B\u0142a\u017cej","family":"Misiak","sequence":"first","affiliation":[{"name":"Department of Psychiatry Wroclaw Medical University  Wroclaw Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wiktor","family":"Grzegorzewicz","sequence":"additional","affiliation":[{"name":"Department of Psychiatry Wroclaw Medical University  Wroclaw Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,26]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"31","volume-title":"Personal Relationships: 3.
